Influential, important and exhilarating live, The Specials are a band embedded in this country’s DNA. It is impossible to envisage the musical landscape without them, from the startling, angular Gangsters in 1979 to their swan song, the epoch-making Lost Town in 1981. They infused ska with punk, homegrown political anxiety with wider issues. The Specials’ ascendancy was swift. Two years, seven hit singles including two number ones, two hit albums, sell-out tours.
